How to solve the problem of power steering pump failure of charging mixer truck?

，转向增压泵不吸油或油压太小。

First of all, the steering booster pump does not absorb oil or the oil pressure is too small.

问题原因：

Cause of the problem:

1.过滤器元件堵塞，由于橡胶的耐腐蚀性，管道堵塞。

1. The filter element is blocked, and the pipeline is blocked due to the corrosion resistance of rubber.

2.管接头处有漏气，空气进入。

2. There is air leakage at the pipe joint and air enters.

3.动力泵部件磨损，间隙过大，导致机油变弱。

3. Wear of power pump parts and excessive clearance lead to oil weakening.

4.油不符合要求或使用时间过长，粘度过大，叶片滑动阻力大。

4. The oil does not meet the requirements or the service time is too long, the viscosity is too high, and the sliding resistance of the blade is large.

5.储油罐中的油位太低。

5. The oil level in the oil tank is too low.

排除方法：

Exclusion method:

1.用酒精清洁滤芯，更换油管，并将液压油添加到指定位置。

1. Clean the filter element with alcohol, replace the oil pipe, and add the hydraulic oil to the designated position.

2.检查紧密连接以防止空气进入。

2. Check tight connections to prevent air from entering.

3.检查并修理增压泵以更换磨损部件。

3. Check and repair booster pump to replace worn parts.

二，转向泵动力泵的工作量太大。

2、 The workload of the power pump of the steering pump is too heavy.

故障原因：进入空气，阀损坏或压力过高，吸油阻力过大。

Fault cause: entering air, damage of safety valve or high pressure, excessive oil suction resistance.

排除方法：

Exclusion method:

1.检查接头的紧固情况，防止空气进入。

1. Check the fastening of the connector to prevent air from entering.

2.修理阀。

2. Repair the safety valve.

3.更换进水管。

3. Replace the water inlet pipe.

操作程序

Safe operation procedure

1.在驾驶之前，您必须仔细检查车辆的状况，以确保车辆能够驾驶。

1. Before driving, you must carefully check the condition of the vehicle to ensure that the vehicle can drive safely.

2.当自上料搅拌车停放在露天时，应在充电前翻转搅拌筒，并排干水和碎屑，以确保混凝土的质量。

2. When the self loading mixer truck is parked in the open air, the mixing drum shall be turned over before charging, and the water and debris shall be drained to ensure the quality of concrete.

3.运输混凝土时，确保倾斜槽牢固放置，防止其因松动而摆动，行人在行驶过程中可能受伤或影响其他车辆的正常运行，同时注意避免混凝土溢出和污染地面。

3. When transporting concrete, ensure that the inclined trough is firmly placed to prevent it from swinging due to looseness, and pedestrians may be injured or affect the normal operation of other vehicles in the process of driving. At the same time, attention should be paid to avoid concrete spilling and polluting the ground.

4.从自上料搅拌车运输混凝土的时间不得超过搅拌站规定的时间。在运输混凝土的途中，搅拌筒不应长时间停止，以防止混凝土分离。驾驶员应始终注意具体情况，并在发现异常时通知主控室并申请。

4. The time for transporting concrete from the self loading mixer truck shall not exceed the time specified by the mixing plant. During the transportation of concrete, the mixing drum shall not be stopped for a long time to prevent concrete separation. The driver should always pay attention to the specific situation and inform the main control room and apply for treatment when abnormal conditions are found.

5.当混凝土安装在车内时，现场的停滞时间不得超过1小时。如果超时，应要求网站负责人及时处理。

5. When the concrete is installed in the vehicle, the site stagnation time shall not exceed 1 hour. In case of overtime, the person in charge of the website shall be required to deal with it in time.

6.当从自上料搅拌车中非抽水时，从混凝土到水箱的时间不应超过2小时，并且必须在超过2小时后排出。当阴雨天气温度低时，不应超过2.5小时。

6. When not pumping from the loading mixer, the time from the concrete to the water tank shall not exceed 2 hours and must be discharged after more than 2 hours. When the temperature is low in rainy weather, it should not exceed 2.5 hours.

7.在排出混凝土之前，搅拌筒应以10-12 rpm的速度旋转1分钟然后排出。

7. Before discharging the concrete, the mixing drum should be rotated at a speed of 10-12 rpm for 1 minute and then discharged.

8.由于自上料搅拌车的进料结束，进料口，卸料斗和卸料槽应冲洗并排干，以去除附着在阀体上的污垢和残留混凝土。保持车辆卫生。

8. Since the feeding end of the loading mixer, the feed inlet, discharge hopper and discharge chute should be flushed and drained to remove dirt and residual concrete attached to the valve body. Keep the vehicle clean.

自上料搅拌车动力转向泵故障的原因和办法就是这样了，希望对你有帮助。
